dc.description.abstractCilj ovoga rada je bio utvrđivanje optimalnog sistema pripreme podloge bukovog drveta (Fagus Silvatica L.) u cilju postizanja viših vrednosti adhezije pojedinih vrsta premaza. Rezultati ispitivanja su pokazali da se obradom drveta brušenjem dobijaju niže vrednosti parametara hrapavosti u površinskom sloju u odnosu obradu drveta glodanjem. Smanjivanje hrapavosti podloge u površinskom sloju rezultovalo je porastom adhezije 2K akril - izocijanatog premaza. Kada je lakiranje vršeno primenom 1K vodorazredivog premaza, više vrednosti adhezije su zabeležene na površinama sa većom hrapavosti podloge. Direktna veza između hrapavosti podloge i adhezije 2K poliuretanskog premaza nije pronađena. Mehanizam adhezije između 1K vodorazredivog premaza i podloge drveta je prvenstveno zasnovan na mehaničkom vezivanju, dok je adhezija 2K akril - izocijanatog premaza i drveta zasnovana na drugim mehanizmima vezivanja.sr
dc.description.abstractIn order to achieve an enhancement of adhesion of specific type of coating to the surface of beech wood (Fagus Sylvatica L.), the optimum substrate preparation system was determined regarding the specific coating formulation. The results showed that lower values of surface roughness parameters can be obtained by the sanding process than by the planning process. These lower values of surface roughness enable higher adhesion of a 2K acrylic-isocyanate coating. In cases where coating is performed with a 1K waterborne coating, higher values of adhesion were observed on the surfaces with higher surface roughness. Direct correlation between surface roughness and adhesion of a 2K polyurethane coating was not found. The adhesion between a 1K waterborne coating and the wood substrate is primarily based on a mechanical bonding (entanglement), while the adhesion of a 2K acrylic-isocyanate coating is primarily based on the other bonding mechanisms.en
